Description

Technical Field

[0001] This utility model specifically relates to a centrifugal separation and recycling device for cotton residue, belonging to the field of cotton residue separation technology. Background Technology

[0002] The slag content of industrial granulated cotton is a core indicator for measuring product quality, directly affecting subsequent processing steps and the performance of the final product. In the production process of industrial granulated cotton, the produced cotton clumps need to be directly or indirectly transported to a granulator, where the slag clumps are separated from the product through the synergistic action of the granulator and the drum screen. However, when cotton clumps and slag clumps enter the granulator together, the slag clumps accelerate the wear of the granulator cutter head and easily break the cotton fibers during movement, resulting in shorter fiber lengths and seriously affecting the subsequent use quality of the product.

[0003] To address the aforementioned issues, existing patent (publication number: CN213447422U) discloses a novel cotton waste separation device. This device includes a first cotton-picking roller with semi-circular spiked teeth on its shaft side, a second cotton-picking roller, a third cotton-picking roller with first rod-shaped spiked teeth, a conveyor belt, a waste waste outlet, a cotton lint outlet, a first motor, a second motor, a third motor, a sieve plate, and adjustable-length second rod-shaped spiked teeth mounted on the sieve plate. Its working principle is that through the cooperation of the cotton-picking rollers, the cotton lint collected and compressed into a cotton blanket by the cotton collector is broken down into small strips of cotton lint, thereby separating out heavy, hard waste balls to protect the normal operation of downstream equipment such as the granulator.

[0004] However, the existing cotton residue separation device still has obvious defects in practical application: On the one hand, the length of the circular nail teeth of the first cotton picking roller with semi-circular nail teeth in the device is fixed, and the length of the nail teeth cannot be flexibly adjusted according to different production needs such as the fluffiness of the cotton and the residue content. This results in poor adaptability to cotton residue separation under different working conditions, and the separation effect is difficult to guarantee. On the other hand, during the operation of the device, cotton fibers are easy to get tangled on the circular nail teeth. Under the existing structure, the machine must be stopped to clean the tangled cotton, which not only affects the continuity of production, but also reduces the overall production efficiency and cannot meet the needs of industrial continuous production.

[0005] Therefore, in view of the above-mentioned shortcomings of existing cotton residue separation devices, there is an urgent need to develop an improved cotton residue separation technology to improve the separation effect and production efficiency. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a centrifugal separation and recycling device for cotton residue.

[0007] A centrifugal separation and recycling device for cotton waste includes a recycling box and a separation box installed thereon. The recycling box has a cotton lint outlet and a waste residue outlet. The top of the separation box has a cotton material inlet. The bottom of the separation box is connected to the recycling box. A separation assembly is installed inside the separation box. The separation assembly includes a first cotton-picking roller, a second cotton-picking roller, and a third cotton-picking roller rotatably disposed inside the separation box. The first and second cotton-picking rollers are arranged in parallel and symmetrical arrangement. The third cotton-picking roller is disposed below the first and second cotton-picking rollers. A third motor for driving the second cotton-picking roller and a fourth motor for driving the third cotton-picking roller are installed on the side wall of the separation box. Multiple conical nail teeth are equidistantly installed on the outer wall of the second cotton-picking roller. Multiple rod-shaped nail teeth are provided on the outer wall of the third cotton-picking roller. Each conical nail tooth can slide radially along the second cotton-picking roller. An adjustment mechanism for adjusting the sliding of the conical nail teeth is also provided inside the second cotton-picking roller.

[0008] Furthermore, the second cotton-picking roller has a roller shaft and a roller body. The adjustment mechanism includes an adjustment screw rotatably installed inside the roller shaft of the second cotton-picking roller. An adjustment nut is threaded onto the adjustment screw. A support rod is provided on the outer wall of the adjustment nut. A connecting rod is hinged to one end of the support rod away from the adjustment nut. The other end of the connecting rod is hinged to one end of the tapered nail tooth extending into the interior of the second cotton-picking roller.

[0009] Furthermore, the second cotton-picking roller has openings on its body, the number of which corresponds to the number of conical nail teeth, and the conical nail teeth are slidably connected inside the openings.

[0010] Furthermore, a conical sleeve is provided on the inner wall of the opening. The conical sleeve is made of rubber, and the outer ring of the conical sleeve fits against the inner wall of the opening. The inner ring of the conical sleeve fits against the outer wall of the conical nail teeth.

[0011] Furthermore, the roller shaft of the second cotton-picking roller is a structure with both ends sealed and the inside hollow. A groove communicating with the inside is provided on the outer wall of the roller shaft. The groove extends along the axial direction of the second cotton-picking roller, and the support rod is slidably connected inside the groove.

[0012] Furthermore, the cotton lint outlet is located on the top wall of the recycling box, the waste residue outlet is located on the bottom wall of the recycling box, the connecting part between the recycling box and the separation box is also provided with a strainer, the inside of the recycling box is symmetrically equipped with conveyor wheels, the inside of the recycling box is equipped with a first motor that drives the conveyor wheels to rotate, and the two conveyor wheels are connected by a conveyor belt.

[0013] Furthermore, the cotton material inlet is provided with a feeding assembly for evenly feeding the cotton material into the separation box. The feeding assembly includes a hopper located on the top of the separation box and capable of sliding horizontally along the length of the separation box. A shaft seat is also installed on the top of the separation box, and a threaded rod is rotatably mounted on the shaft seat. A second motor that drives the threaded rod to rotate is installed on the top of the separation box. A threaded seat is threadedly connected to the threaded rod, and the threaded seat is fixedly connected to the outer wall of the hopper.

[0014] Furthermore, there are two threaded rods, which rotate symmetrically on the top of the separation box. Each of the two threaded rods is equipped with a synchronous pulley, and a synchronous belt connects the two synchronous pulleys.

[0015] Beneficial effects:

[0016] 1. This utility model achieves flexible and precise adjustment of the protrusion length of the nail teeth through the adjustable conical nail teeth of the second cotton picking roller and the matching adjustment mechanism. The disassembly force can be dynamically adjusted according to different working conditions such as the fluffiness of the cotton material and the amount of slag. The coordinated graded disassembly of the first cotton picking roller, the second cotton picking roller and the third cotton picking roller greatly improves the efficiency and purity of slag ball separation, and effectively reduces the wear of slag balls on the subsequent granulator cutter head and the problem of cotton fiber breakage.

[0017] 2. In this utility model, the sliding hopper driven by the double threaded rod ensures that the cotton material is evenly spread to the separation component, avoiding incomplete separation caused by local accumulation.

[0018] 3. In this invention, when cotton fibers become entangled on the conical nail teeth of the second cotton-picking roller, cleaning can be completed without stopping the machine, simply by adjusting the mechanism: rotating the adjusting screw inside the roller shaft of the second cotton-picking roller causes the adjusting nut to move axially. The adjusting nut pulls the connecting rod through the support rod, thereby driving the conical nail teeth to slide inward along the opening and finally be drawn into the second cotton-picking roller. The cotton fibers entangled on the conical nail teeth lose their support and fall off under their own weight and the airflow in the separation box. They are then discharged through the subsequent separation process, achieving online cleaning without stopping the machine, effectively avoiding production interruptions, further improving production efficiency, and reducing manual maintenance costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, a centrifugal separation and recycling device for cotton waste includes a recycling box 1 and a separation box 2 installed thereon. The recycling box 1 is provided with a cotton lint outlet 3 and a waste residue outlet 4. The top of the separation box 2 has a cotton material inlet 8, and the bottom of the separation box 2 is connected to the recycling box 1. A separation assembly is provided inside the separation box 2. The separation assembly includes a first cotton-picking roller 14, a second cotton-picking roller 15, and a third cotton-picking roller 17, which are rotatably arranged inside the separation box 2. The first cotton-picking roller 14 and the second cotton-picking roller 15 are arranged in parallel and symmetrically, and the third cotton-picking roller 17... Located below the first cotton-picking roller 14 and the second cotton-picking roller 15, the separation box 2 has a third motor 16 for driving the second cotton-picking roller 15 to rotate and a fourth motor 18 for driving the third cotton-picking roller 17 to rotate. Multiple conical nail teeth 24 are equidistantly installed on the outer wall of the second cotton-picking roller 15, and multiple rod-shaped nail teeth 19 are provided on the outer wall of the third cotton-picking roller 17. Each conical nail tooth 24 can slide radially along the second cotton-picking roller 15. An adjustment mechanism for adjusting the sliding of the conical nail teeth 24 is also provided inside the second cotton-picking roller 15.

[0027] Specifically, the length of the nail teeth can be flexibly adjusted according to the requirements of cotton fluffiness and slag content through the sliding conical nail teeth 24 and the adjustment mechanism, thereby improving the adaptability to different working conditions; the layout of the three-stage cotton picking rollers realizes the grading and disassembly and separation of cotton materials, improves the efficiency of slag ball separation, and reduces the wear on the subsequent granulator; the connection design between the recycling box 1 and the separation box 2 realizes the synchronous separation and recycling of cotton and slag balls, simplifying the production process.

[0028] As a technical optimization of this utility model, the second cotton picking roller 15 has a roller shaft and a roller body. The adjustment mechanism includes an adjustment screw 21 rotatably installed inside the roller shaft of the second cotton picking roller 15. An adjustment nut 25 is threadedly connected to the adjustment screw 21. A support rod 26 is provided on the outer wall of the adjustment nut 25. A connecting rod 28 is hinged to one end of the support rod 26 away from the adjustment nut 25. The other end of the connecting rod 28 is hinged to one end of the conical nail tooth 24 that extends into the interior of the second cotton picking roller 15.

[0029] Specifically, the adjusting screw 21 is rotatably mounted inside the roller shaft and threadedly connected to the adjusting nut 25; the adjusting nut 25 is connected to the connecting rod 28 via the support rod 26, and the other end of the connecting rod 28 is hinged to the inner end of the conical nail tooth 24. When the adjusting screw 21 is rotated, the adjusting nut 25 moves axially, which drives the connecting rod 28 to push and pull the conical nail tooth 24 through the support rod 26, thereby realizing its radial sliding along the second cotton picking roller 15, i.e., length adjustment.

[0030] As a technical optimization of this utility model, the second cotton picking roller 15 has an opening on its roller body, the number of openings corresponding to the conical nail teeth 24, and the conical nail teeth 24 are slidably connected inside the opening.

[0031] Specifically, the opening provides guidance for the radial sliding of the tapered spike teeth 24, limiting their offset direction.

[0032] As a technical optimization of this utility model, a conical sleeve is provided on the inner wall of the opening. The conical sleeve is made of rubber. The outer ring of the conical sleeve fits against the inner wall of the opening, and the inner ring of the conical sleeve fits against the outer wall of the conical nail tooth 24.

[0033] Specifically, the conical sleeve utilizes the elasticity of the rubber to form a seal as the conical nail teeth 24 slide.

[0034] As a technical optimization of this utility model, the roller shaft of the second cotton picking roller 15 is a structure with both ends sealed and the inside hollow. A groove 27 communicating with the inside is provided on the outer wall of the roller shaft. The groove 27 extends along the axial direction of the second cotton picking roller 15, and the support rod 26 is slidably connected inside the groove 27.

[0035] Specifically, when the adjusting nut 25 moves axially, the support rod 26 slides along the slide groove 27, restricting the adjusting nut 25 to rotate synchronously with the screw and only move axially.

[0036] As a technical optimization of this utility model, the cotton lint outlet 3 is set on the top wall of the recycling box 1, the waste residue outlet 4 is set on the bottom wall of the recycling box 1, the connecting part between the recycling box 1 and the separation box 2 is also provided with a strainer 20, the inside of the recycling box 1 is symmetrically rotated and equipped with conveyor wheels 6, the inside of the recycling box 1 is equipped with a first motor 5 that drives the conveyor wheels 6 to rotate, and the two conveyor wheels 6 are connected by a conveyor belt 7.

[0037] Specifically, the separated slag balls and cotton fibers pass through the perforated plate 20 and fall into the bottom of the recycling box 1, and are discharged through the waste slag outlet 4; the cotton fibers are pushed to the conveyor belt 7 and transported by the conveyor belt 7 to the cotton fiber outlet 3 for discharge.

[0038] As a technical optimization of this utility model, a feeding component is provided on the cotton inlet 8 to uniformly feed the cotton into the separation box 2. The feeding component includes a hopper 9 set on the top of the separation box 2 and capable of sliding horizontally along the length of the separation box 2. A bearing seat 10 is also installed on the top of the separation box 2. A threaded rod 11 is rotatably installed on the bearing seat 10. A second motor 12 is installed on the top of the separation box 2 to drive the threaded rod 11 to rotate. A threaded seat 13 is threadedly connected to the threaded rod 11. The threaded seat 13 is fixedly connected to the outer wall of the hopper 9.

[0039] Specifically, the second motor 12 drives the threaded rod 11 to rotate, and the threaded seat 13 drives the hopper 9 to slide along the length of the separation box 2, so as to evenly feed the cotton material into the separation box 2.

[0040] As a technical optimization of this utility model, two threaded rods 11 are provided. The two threaded rods 11 rotate symmetrically on the top of the separation box 2. Synchronous pulleys 22 are installed at the ends of the two threaded rods 11, and a synchronous belt 23 is connected between the two synchronous pulleys 22 for transmission.

[0041] Specifically, when the second motor 12 drives either threaded rod 11 to rotate, the two threaded rods 11 rotate synchronously through the synchronous pulley 22 and the synchronous belt 23.

[0042] This device achieves efficient separation and recovery of cotton fibers and lint from cotton feed through the coordinated operation of the feeding component, separation component, and recovery conveying mechanism. The specific workflow is as follows:

[0043] The cotton material to be separated is fed into the cotton material inlet 8 at the top of the separation box 2. The second motor 12 is started to drive the threaded rod 11 to rotate. Since the threaded seat 13 is threadedly connected to the threaded rod 11 and fixed to the hopper 9, the rotation of the threaded rod 11 causes the hopper 9 to slide horizontally along the length of the separation box 2. At the same time, the two threaded rods 11 rotate synchronously through the synchronous wheel 22 and the synchronous belt 23 to ensure that the hopper 9 moves smoothly and spreads the cotton material evenly on the separation components inside the separation box 2, laying the foundation for subsequent uniform separation.

[0044] Preliminary disassembly and separation: The third motor 16 is started to drive the second cotton picking roller 15 to rotate. The first cotton picking roller 14 and the second cotton picking roller 15 rotate in parallel and symmetrically. The conical nail teeth 24 on the outer wall of the roller initially disassemble the evenly falling cotton material, breaking the clumps of cotton material into small pieces of cotton wool. At the same time, taking advantage of the large weight and high hardness of the slag balls, some larger slag balls are initially separated. According to the working conditions such as the fluffiness of the cotton material and the slag content, the length of the conical nail teeth 24 can be adjusted by adjusting the mechanism: Rotate the adjusting screw 21 inside the roller shaft of the second cotton picking roller 15 to drive the adjusting nut 25 to move along the roller shaft axial direction. The adjusting nut 25 pulls the connecting rod 28 through the support rod 26, thereby driving the conical nail teeth 24 to slide radially along the second cotton picking roller 15. The rubber conical sleeve on the inner wall of the opening plays a guiding and sealing role. The sliding groove 27 provides guidance for the movement of the support rod 26, realizing flexible adjustment of the nail tooth extension length and improving adaptability to different working conditions.

[0045] Deep separation and purification: The fourth motor 18 is started to drive the third cotton picking roller 17 to rotate. The third cotton picking roller 17 is located below the first cotton picking roller 14 and the second cotton picking roller 15. The rod-shaped nail teeth 19 on its outer wall disassemble and comb the cotton material after preliminary separation, and completely separate the remaining small slag balls from the cotton. The external negative pressure equipment is connected to the cotton slag outlet 3 and the waste slag outlet 4 respectively. The pressure at the cotton slag outlet 3 is less than that at the waste slag outlet 4. Under the action of negative pressure, the separated slag balls and strip-shaped cotton slag pass through the perforated plate 20 at the connection between the separation box 2 and the recycling box 1 and fall to the bottom of the recycling box 1 and onto the conveyor belt 7 inside the recycling box 1. The first motor 5 is started to drive the conveyor wheel 6 to rotate, which drives the conveyor belt 7 to run. Under the action of negative pressure, the cotton slag is transported to the cotton slag outlet 3 on the top wall of the recycling box 1 for discharge, completing the cotton slag recycling. The slag balls deposited at the bottom of the recycling box 1 are discharged through the waste slag outlet 4 on the bottom wall, realizing the recycling treatment of the slag balls.
